A brief summary of findings from operating Seafury Surface drives on MV Pure Adrenalin. I have been operating Pure Adrenalin for over 3 years and have found the manoeuvrability of the vessel from the thrust given from these drives excellent. The thrust given at both forward and astern at idle is suitable for any manoeuvring and in and out of berth. Enough thrust is given when parking astern from one side (in up to moderate conditions) to prevent from having to use bow thrusters or the opposing motor to screw the vessel.
We had a charter last night with rainsqualls and wind gusts up to 48 knots. I had to berth Pure Adrenalin in 38 knots at Marina Mirage in a very tight berth, with 50 guests onboard all eyes watching and comments of, 'They'll never park it in there', and with another vessel beside us no further away than 3 feet. Another confident manoeuvre and again a tribute to the astern propulsion from the drives.
At speeds of 26 knots she is using 350 litres/hour total and cruises at 21 knots using approximately 250 litres/hour and for a 27m catamaran we are very happy with its performance. When the vessel is both in and out of the water, the drive units and propellers are very accessible to clean, inspect and maintain.
